In cell culture biology, confluence is the term commonly used as an estimate of the number of adherent cells in a culture dish or a flask, referring to the proportion of the surface which is covered by cells.or example, 50 percent confluence means roughly half of the surface is covered and there is still room for cells to grow. 100 percent confluence means the surface is completely covered by the cells, and no more room is left for the cells to grow as a monolayer.
One of the few external rigid points on the GZ-20âs envelope, it holds the battens, attachments for the nose lines and the mooring spindle. 2. Material. The largest component of the Blimp, the GZ-20âs envelope is made of two-ply, neoprene-impregnated polyester fabric. 3. Ballonet. Located in the forward and aft of the envelope, these air bags allow the pilot to regulate the amount of helium in the Blimp and statically trim the ship in a nose-up or nose-down situation.
All technical data of the New Goodyear Blimp refer to the Zeppelin model LZ N07-101. Blimp Facts: Science & Technology. Without its lifting gas, an empty GZ20A weighs about 12,840 lbs. Once inflated with helium and after accounting for fuel, payload and ballast, it usually weighs in at 100-200 lbs.ot technically a Blimp but a semi-rigid airship, the new Goodyear Blimp was born in the storied hangar at Wingfoot Lake in Akron, Ohio. It is the first ever semi-rigid airship to be constructed there.
